Ellison opened Oracle OpenWorld by helping introduce several new hardware systems highlighted by an in-memory database technology he claimed improves database query speed by 100 times with no changes to the applications.

Ellison said the new high-performance solutions fit his vision of the data center of the future, which depends on specialized machines that offer the best cost/performance ratio, increase reliability and security, and are easy to use.

"You spend less buying it," he said. "You use less floor space to hold it. You use less electricity to run it. And it's all pretested, so it's much more reliable."

Ellison said Oracle's new in-memory database technology, which is available as an option for the company's Exadata database engineered system, lets users of the Exadata database engineered system merely specify many gigabytes of memory to allocate to the database and configure the tables and partitions.
